Republicans used to believe that prosperity depended upon the regular balancing of accounts — in government, in international trade, on the ledgers of central banks and in the financial affairs of private households and businesses, too. But the new catechism, as practiced by Republican policymakers for decades now, has amounted to little more than money printing and deficit finance — vulgar Keynesianism robed in the ideological vestments of the prosperous classes…

The second unhappy change in the American economy has been the extraordinary growth of our public debt. In 1970 it was just 40 percent of gross domestic product, or about $425 billion. When it reaches $18 trillion, it will be 40 times greater than in 1970. This debt explosion has resulted not from big spending by the Democrats, but instead the Republican Party’s embrace, about three decades ago, of the insidious doctrine that deficits don’t matter if they result from tax cuts.

In 1981, traditional Republicans supported tax cuts, matched by spending cuts, to offset the way inflation was pushing many taxpayers into higher brackets and to spur investment. The Reagan administration’s hastily prepared fiscal blueprint, however, was no match for the primordial forces — the welfare state and the warfare state — that drive the federal spending machine.

Soon, the neocons were pushing the military budget skyward. And the Republicans on Capitol Hill who were supposed to cut spending exempted from the knife most of the domestic budget — entitlements, farm subsidies, education, water projects. But in the end it was a new cadre of ideological tax-cutters who killed the Republicans’ fiscal religion.

Buckley’s National Review, where I was the literary editor through the 1990s, remains as vital and interesting as ever. But more characteristic of conservative leadership are figures on TV, radio and the Internet who make their money by stirring fears and resentments. With its descent to baiting blacks, Mexicans and Muslims, its accommodation of conspiracy theories and an increasing nastiness and vulgarity, the conservative movement has undergone a shift toward demagoguery and hucksterism. Once the talk was of “neocons” versus “paleocons.” Now we observe the rule of the crazy-cons…

When I became a conservative, that is what I signed up for: a profound vision granting transcendent significance to public life and hope in private life. The goal wasn’t to defeat Democratic officeholders or humiliate left-wing activists. It was, and still is, with those who remember, to save civilization.
